RAILWAY-SWITCH.

This invention relates to certain new and.

useful improvements in railway switches and has particular reference to that type of switch wherein the rail sections of a switch are bodily moved for alining the switch rail sections with stationary rail sections.

The primary object of the invention resides in the provision of a railway switch wherein a plate having the switch rail sections secured thereto is bodily shiftable transversely of the track for alining the different rail points with the stationary rail sections.

With the above general objects in view and others that will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described and shown in the accompanying drawings, in which like reference characters designate corresponding parts throughout the several views.

In the drawings,

Figure 1 is a top plan view of a railway switch constructed in accordance with the present invention showing the switch rail sections fixedly secured to a transversely shiftable plate,

Fig. 2 is a cross sectional view taken on line II-II of Fig. 1 showing the switchrail sections secured to a transversely shiftable plate with the lever arm and link for shifting the plate,

Fig. 3 is a longitudinal sectional. view taken on line III-III of Fig. 1 showing the transversely shiftable plate anchored to the mounting base plate therefor,

Fig. 4 is a detail sectional view taken on line IV-IV of Fig. 1 showing the switch rail sections anchored to the shiftable plate,

Fig. 5 is a perspective view of the mounting base plate, and

Fig. 6 is a perspective view of the shift able switch point supporting plate and a portion of the operating link.

Referring more in detail to the accompanying drawings and particularly to Fig. 1,

Specification of Letters latent. Patented A 23 1921 Application filed May 5, i

1921. Serial N0. 466,953.

there is illustrated a portion of a railway track wherein a supporting tie 1 has longi tudinal track rails 2 secured thereto, I a spaced supporting tie 3 having rails 4 alined with the rails 2 and switch rails 5 supported onlthe tie 3 at the usual divergence of switch rats.

The switch rail sections are interposed between the rails 2 and. 4t--5, and are supported on a transversely shiftable plate for alining either pairs of switch rail sections with the rails 24, or 25. Supporting ties 6 interposed between the ties 1 and 3 have mounted thereon the base plate 7 shown in detail in Fig. 5 as provided with upwardly directed offset end extensions 8 resting on the ties 6 and secured thereto by suitable bolts as indicated at 9, the offset extensions 8 being cut away intermediate their ends as at 10 to accommodate the fastening bolts 9. As shown in Fig. 1, the adjacent ends of the rails 2, 4;, and 5 are anchored to the ties 6.

The supporting plate 11 shown in detail. in Fig. 6 carries upon the lower face thereof, a pair of longitudinally extending cleats 12 that are received in elongated openings 12 formed in the base plate 7 the openings 12 being of greater length than the cleats to provide for a sliding movement of the plate 7 this movement being limited by the ends oi. the cleats engaging the end walls oi the openings 12. To anchor the switch supporting plate 11 to the base plate 7 for slid-- ing movement relative thereto, and. against upward movement transverse strips 13 underlying the baseplate 7 are secured by bolts 14 to the cleats 12, this connection permitting a free sliding movement of the plate 11 relative to the base plate? but preventing a separating movement thereof, this latter construction being clearly shown in Figs. 2 and 3. y y

The switch rails embody parallel sections 15 adapted for alining with the track rails 2 and 4 and parallel diverging sections 16 adapted for alining with the track rails 2 aud5, the switch rails 15 and 16 being auchored to the plate 11 by bolts 17 passing through openings 18 in the plate 11 and carrying nuts 19 or other retaining devices for engaging the base flanges of the switch rails 15 and 16. i

To shift the plate 11 transversely of the track, and upon the base plate 7, a link rod 20 has one end pivotally connected to a lug 21 carried by the bottom face of the plate 11 movement bein and extending through a slotted opening 21 in the base plate 7 with the free end of the link rodsliding through an opening provided in the bar 22 secured between the supporting ties 6 as clearly shown in Figs. 1 and 2. A bell crank 23 pivoted asat 24 has one end thereof provided with a slotted openin 25 for receiving a pin 26 projecting upwar ly from the link rod 20 while the other end ofthe bell crank 23 has an operatin rod 27 attached thereto. V

n the operation of the device, assuming that the switch points upon the plate 11 are in the positionshown 1n Fi .1, with the switch rails 15 alined with t e track rails 2 and 4, and it bein desired to aline the openings. Any perpendicular movement of the plate ll'relative to the base plate 7 is eliminated by the strips 13 secured to the cleats 12- and underlying the base plate 7 as shown in Figs. 2 and? While there is herein shown and described the preferred embodiment of the invention,

it is nevertheless to be understood that minor changes maybe made without departing from the spirit and scope of the invention as herein claimed. r

What is claimed as new is:

- 1. A railway switch of the type-described comprising in combination with fixed rail sections, a rigidly mounted base plate, a switch rail supporting plate slidably mounted on the base plate and adapted to bodily move the switch rails for alining with the fixed rail sections and cooperating means carried by the base plate and switch rail supporting plate for limiting the movement of theswitch rail supporting plate, said means including elongated openings formed in the base plate and cleats carried by the other plate received in said openingsand of less length'than said openings.

- 2. A railway switch of the type described comprising in combination with fixed rail sections, a rigidly mounted base plate, a switch rail supporting plate slidably mounted on the base plate and adapted to bodily moveth'e switch rails for alining with the fixed rail sections and cooperating means carried by the base plate and switch rail supporting plate for'llmiting the movement of the sw tch railsupporting plate, said means including elon ate openings formed in the baseplate an cleats carried by the other plate received in said openings and of less length than said openings and means carried by said switch rail supporting plate coiiperating with the base plate to prevent perpendicula r movement of the switch rail supporting plate relative to the base plate.

3. A railway switch of the type described comprising in combination wlth fixed rail sections, a rigidly mounted base plate, a switch rail supporting plate slidably mounted on the base plate and adapted to bodily move the switch points for alining with the fixed rail sections and cotiperating means carried by the base plate and switch rail sup porting plate for limiting the movement of the switch rail supporting plate, said means including elongated openings formed in the base plate, cleats carried by the other plate received in said openings and of less length than said openings, means carried by said switch rail supporting plate cooperating with the base plate to prevent erpendicular movement of the switch rail supporting plate relative to the base plate and means for shifting the switch rail supporting plate.

4. A railway switch of the type described comprising in combination with fixed rail sections, a rigidly mounted base plate, a switch rail supporting plate slidably mounted on the base plate and adapted to bodily move the switch rails for alining with the fixed rail sections and cooperating means carried by the base plate and switch rail supporting plate for limiting the movement of the switch rail supporting plate, said means including elongated openings formed in the base plate and cleats carried by the other plate received in said openings and of less length than said openings, means carried by said switch rail supporting plate cooperating with the base plate to prevent perpendicular movement of the switch rail supporting plate relative to the base late, a link rod attached to the switch rai supporting plate and a bell crank associated with said link rod for shifting the same and the plate with the switch rails carried thereby.
